The Third Party
Known as "The Third Party" in the battle over Mu. The group actually finds the title offensive, as they see a much bigger picture and find Mu trivial. They coined their faction name from the term "Third Party Organization" as a type of pun.
Although the faction originally stemmed from their first branch, Arx, led by the notorious, Akira, they began to expand and create other factions. There are rumors that these branches go out as far at the 8th Mortal Realm.
